Finn is revealed to regularly have alone time with the wad of Princess Bubblegum’s hair she gave him in “To Cut a Woman’s Hair”. It’s essentially a PG version of a guy still holding on to their ex’s underwear for personal use. The allegory is pushed forward with Finn checking to make sure he is alone. Don’t get me wrong, this isn’t exactly shocking behavior for a thirteen year old boy, but it’s the first big sign that Finn’s crush is getting unhealthy after “Too Young”. It’s time to move on! Unlike “Wizard Battle”, I like the incorporation of Finn’s feelings, despite the arc feeling like there’s nowhere to go after “Too Young”. It’s not the main conflict in the episode, and serves to build to a climax in the season finale.
The Door Lord steals Finn’s gum, Jake’s blanket, and BMO’s controller. It’s hilarious that he only speaks in loud mumbles. He’s supposed to be related to Key-per from “The Enchiridion!”. The Door Lord steals a toy from a candy person and Finn reassures him “I’ll get your kid back, toy!”. The episode wasn’t originally written this way. Adam Muto misspoke when he was pitching the episode and they thought it was funny to keep it like that. Door Lord steals something from Bubblegum and attempts to steal Marceline’s bass axe. With Maja being in possession of Hambo, it makes sense for her bass axe to be her most important item. Finn, Jake, Princess Bubblegum, Marceline, and BMO have to team up to solve the riddle of the door. It’s great getting to see this group of characters together for the first time. It’s the entire main cast minus Ice King, and they get so few opportunities to all be together before Stakes. Their group dynamic is so fun too. The episode is set in Red Rock Pass, which is a really pretty setting to choose for a (mostly) bottle episode.
Marceline chastises Bubblegum for not executing the door lords, as they kept breaking out of jail. I’m not sure if PB is really above just killing them, considering all the fucked up stuff she’s done in the past. But, killing might be a bridge too far for her. I know she committed robot genocide, but I argue she didn’t see them as sentient beings. Jake decides to pretend to be the jerk in the band. Since Jake doesn’t have a grand emotional arc, this is a funny role to put him in. Marceline starts singing “Just Your Problem”:
-“I’m gonna drink the red from your pretty pink face”. This pretty much gives the game away about PB and Marcy not being platonic. She’s singing about kissing and biting PB.
-PB calls it “distasteful”, causing Marceline to accuse her of just not liking her. This ties into PB not liking Marceline’s behavior when she got more and more consumed with her princess duties. Marceline became well aware of this by their first mission to the Glass Kingdom (“Oh c’mon, you love it.”).
-“Sorry I don’t treat you like a goddess. Is that what you want me to do?” She’s calling out PB’s god complex. Marceline assumes Bonnie thinks she’s better than her, like how she sings “you’re self-obsessed and all the rest” in Distant Lands.
-“Sorry I don’t treat you like you’re perfect, like all your little loyal subjects do. Sorry I’m not made of sugar. Am I not sweet enough for you?”. Marceline thinks Bubblegum demands absolute loyalty from everyone as she does with her citizens. She thinks PB would prefer Marceline to be a dum dum juiced moron that never questions her. We don’t know if Marceline is aware of the dum dum juice, but I like to think that she’s partially referring to that. It also relates to Marcy viewing PB as a dictator as she sings in “Woke Up”. She thinks PB wants her to turn down her edginess and be sweeter, like when she wasn’t taking the situation in the Glass Kingdom seriously, something I’m sure wasn’t an isolated incident.
-I’ll lump together “Is that why you always avoid me?” with the later line “I forgot what landed me on your blacklist.” Some people question why Marceline wonders this considering her singing “Woke Up” is the obvious answer. I think she’s partially referring to PB’s actions before their breakup. Bubblegum grew more distant as her responsibilities grew, something that confused and hurt Marceline. PB talks about this in “Varmints”. She’s also referring to PB being cold to Marceline for centuries after their breakup. Even when they were around each other in “Power Animal” and “Video Makers”, we don’t see them talking. Bubblegum was very dismissive of Marcy in “Go With Me”. This is partially Marceline’s fault, as she can be really rude and mean to Bonnie, as seen in this episode.
-“I shouldn’t have to justify what I do.” Marceline doubles down on acting the way she thinks people perceive her. If people think she’s a monster, it's less painful for her to embrace it. This is something she picked up on from thinking she scared her mother away.
-“I shouldn’t have to be the one who makes up with you so why do I want to…” Marceline thinks that since PB is the one who pushed her away, PB is the one who should take the initiative of making things right. There is some truth to this, but as we see in “Obsidian”, they are both more at fault than Marcy is willing to admit. The faces on the door glow brighter and Marceline gets closer to the truth. The truth is she wants to at least be friends with Princess Bubblegum again. That’s the real reason she joined the group here. Reconnecting to PB is something we’ll see her try to do in episodes like “Sky Witch”, “Princess Day”, and “Varmints”.
The song itself slaps. “Just Your Problem” is super popular, so much so that tons of non-fans know the song. A big reason being that it’s probably the most relatable Adventure Time song ever. A lot of people have friends and lovers that drifted away from them or became downright cold to them due to their differences. Rebecca Sugar even based the song off of her experience with a roommate. Princess Bubblegum’s face during this is also pretty telling. She was definitely having flashbacks to the last time Marceline humiliated her with a song. PB’s face turns to shock when Marceline is on the verge of revealing she wants to make up with her. I don’t blame Bonnie for not realizing this. Marceline’s general nastiness towards her, and of course what she said about her while singing “Woke Up”, would give PB the opposite impression.
Finn doesn’t fully grasp the tension between PB and Marcy, but is able to diffuse the awkwardness and get everyone (besides Jake) to have fun together. I also like how sweet Marceline is to BMO, gently calling him “baby”. I like PB’s quirky attempt at a science based song, which is more fitting for her than singing her heart out like Marceline and Finn. Her song fails and Marceline uses it to antagonize PB. She fixates on Bonnie’s failures as she feels insecure in her presence. The words “monster trash” are definitely echoing in her mind here. Marceline is still really nasty to PB. A lot of it feels like unwarranted bullying without the context of future episodes, but even with the context, it still feels that way to an extent. Spitting on PB is pretty inexcusable and Bubblegum is totally right to walk away after it. Their conflict boils down to Princess Bubblegum’s ego and Marceline’s insecurity clashing. I also like the detail of Shelby slithering back into Jake’s smashed viola.
As a final effort, Finn sings “My Best Friends in the World” after realizing the key to the door is the truth:
-“Am I a joke…?” Finn worries that Marceline doesn’t respect Finn, and perhaps only hangs around him because she enjoys messing with him. This is an understandable fear with episodes like “Henchman”. It’s still fundamentally untrue, squashed by the end of “Henchman” and in “Heat Signature”. There is no denying, however, that she loves trolling Finn. She likes messing with everyone, Finn’s young mind just makes him an easier target.
-“...your knight…?” This could be taken to mean Finn wonders if PB only keeps him around, and entertains his advancements, just to use his service to the kingdom. It’s true that Bubblegum employs Finn a lot, and isn’t above manipulating him for her benefit (“The Other Tarts”, “Too Old”, “James”), but she still genuinely enjoys his company whether they are working or just hanging out. He might also just be referring to this positively, as her knight in shining armor.
-“Do you look down on me because I’m younger?” All of Finn’s closest companions are older than him, and it makes sense that this weighs on him. Even Jake, who is often close to Finn’s level and acts as a best friend, also often acts as his parental guardian. This line applies most of all to Bubblegum, given how recent “Too Young” is. The events of that episode are still raw for Finn, and PB’s behavior to him after her age was restored came across as condescending and dismissive.
-“I just wanted us together and to play as a band. Last night was the most fun I’ve ever had.” Finn loves getting to finally hang out with everyone he loves together and feeling like part of a family.
-“Even liked it when the two of you would get mad at each other.” Finn prefers honesty between friends, and appreciates seeing their more vulnerable side as they are usually more closed off from their true emotions in front of him.
-“You are my best friends in the world. And that’s right, I’m talking about the two of you girls. And you Jake.” With his parents dead, the three of them are by far his closest companions. He’s even grown very close to Marceline in recent times. It’s kinda mean to exclude BMO, who’s right there, but BMO becomes more of a part of Finn’s family over time than he is here.
-“I’ll forget that I lost a piece of your hair. I’ll remember the pasta that we shared over there”. Very sweet line about how the wad of hair doesn’t really matter, the time he spends with PB and getting to be her friend is what’s meaningful to him. I like how the pasta has a double meaning. He obviously just shared pasta with her, but he also had a pasta dinner with Bubblegum when she gave him the hair.
Finn’s song is my favorite moment of the series so far, and one of the best scenes ever in the series. I thought “Just Your Problem” was Adventure Time’s best song up to now but it’s then immediately topped. I love everyone participating in the song, especially Marceline singing along with Finn for parts of it. Finn’s song causing even PB and Marcy to harmonize together is great symbolism for Finn helping to bring them back together. Even Jake finally breaks character, he’s too caught up in the moment! Rebecca Sugar drew on her feelings of being a young newcomer when she joined the Adventure Time staff to write this song. Worrying about how your friends see you and if they respect you is another very ubiquitous concern.
The group realizes that the Door Lord showed them that the real treasure is friendship. It’s very cheesy but the contents of the episode does enough to justify it. It’s cool how well the episode ties two themes into this episode: friendship and honesty. The quick cut from the Door Lord happily seeing they got the message to him being bruised and tied up is hilarious. They get their items back, including the famous rock shirt. It’s not at all PB’s style, going to show how much its pure sentimentality means to Bubblegum. The reveal that PB kept the shirt comes as a shock to Marceline. She realizes that Bonnie doesn’t see her as just her problem. Marceline blushing and PB revealing she wears the shirt all the time as pajamas are heavy hints to their romantic pairing. Their interactions in this episode are very queer-coded, even though they aren’t hitting us over the head with it like they do in season 7 onwards. The episode itself gives enough to figure out the broad strokes of Marceline and Bubblegum having a past and a falling out without giving the details, and it’ll be a long time until they are willing to explore it more at all. It’s revealed that Marceline only joined to hang out with them. Beyond reinforcing the theme of friendship, Marceline and PB now know that the other is interested in reforming a connection again, even if Marceline will have to be the one that ends up instigating it.
“What Was Missing” is a fan favorite for good reason. The two musical numbers are the biggest draw and they are incredible. Rebecca Sugar using her own personal experiences to write them makes them feel so raw and personal. It’s some of the most direct the series ever is about Marceline and especially Finn’s thoughts and feelings, with them explicitly singing them. It’s refreshing to get some clear cut insight as the show is usually much more guarded. I wouldn’t want the series to always be this direct, but it's nice to have moments like these every once in a while to help provide insight into their other appearances. The episode is essentially a precursor for Steven Universe. You could slot in Steven for Finn, Pearl for Bubblegum, and Amethyst for Marceline quite easily. I also really like PB in this one! Despite “What Was Missing” having not one, but two characters that are in love with Princess Bubblegum, she gets to shine. It’s definitely more Marceline-heavy, but I like PB standing up for herself, getting to see her side of the conflict, and the return of her quirks with her scientific song. PB and Marceline also have pretty great outfits here, and it’s definitely their most iconic looks besides their default outfits.
Rebecca Sugar has since stated that she wrote PB and Marcy as exes in this episode. She felt their interaction in “Go With Me” read that way. The episode does a great job extrapolating from that brief interaction. According to Rebecca Sugar, she pitched this idea to Adam Muto, who she boarded the episode with, and he approved. They ran this by Pen who also liked it. Cartoon Network forbade the crew from being explicit with it. They still did a good job making it as clear as they could with the restrictions and the fandom picked up on it. Rebecca Sugar wanted to include LGBTQ representation and felt that exploring it through the lens of two exes with a past was the best path to getting it in. Despite it only being subtextual, it was a big deal for 2011.
This episode stirred up quite the firestorm. It’s possibly not a coincidence that it would take almost two years for PB and Marcy to interact again. The Fredator associated Youtube channel Mathematical! posted recaps after the airing of Adventure Time episodes. After the airing of “What Was Missing”, their recap speculated on the possible romantic pairing between Princess Bubblegum and Marceline, interlaced with overtly romantic drawings of Marceline and Bubblegum from character designer and storyboard revisionist Natasha Allegri. As a result, Fredator fired Mathematical! producer Dan Rickmers, deleted the video, and cancelled the Youtube series. Times were different then, but that’s no excuse for such an overreaction. Fred Seibert offered the following explanation:
“Well, I completely screwed up. There’s been chatter on the internet recently about our latest Adventure Time “Mathematical!” video recap that we created, posted, and removed here at Federator. I figure it’s time to clear up the matter. In trying to get the show’s audience involved we got wrapped up by both fan conjecture and spicy fanart and went a little too far. Neither Cartoon Network nor the Adventure Time crew had anything to do with putting up or taking down our latest re-cap. The episode ”What was Missing” remains a terrific short and will be shown again and again just like any other Adventure Time episode. I let us goof in a staggering way and I’m deeply sorry it’s become such a distraction for so many people.” It’s a really weak reasoning as Mathematical! had always been a fan oriented show and that’s what the entire fandom was talking about. Still, I’d expect this from an executive. What was unexpected were Adam Muto’s comments:
“If it was just a fan video there would be no problem at all. The problem was that it was made by a production company actively involved with the show. The video took something that was a possible subtext and declared it, in effect, text and made it seem like the production was actively seeking out input on plot development. That's all there is to it.” Considering Sugar said that Adam Muto agreed with that interpretation, it would have been for the best if he just stayed out of the situation. That’s what Pen Ward did ("It’s hard to comment on that, because there were so many extreme positions taken on it all over the Internet, and it happened so quickly. I don’t really want to comment on it because of that, because there were so many extreme sides taken. It was a big hullaballoo.")
Now that we know Bubbline was in fact the crew’s intention, and it’s since been explicitly canonized, the situation is just even dumber. Dan Rickmer is definitely owed an apology. But what’s really important is the series no longer having to keep their relationship a big secret.
